title: Marvell MMP2 and MMP3 Clock Controller

maintainers:
  - Lubomir Rintel <lkundrak@v3.sk>

description: |
  The clock subsystem on MMP2 or MMP3 generates and supplies clock to various
  controllers within the SoC.

  Each clock is assigned an identifier and client nodes use this identifier
  to specify the clock which they consume.

  All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.
